How and why the health insurance system will collapse.

The advocates of defined-contribution health plans extol the virtues of consumer-driven health care, consumer choice, and empowered consumers as solutions to the problems--particularly the rapidly growing costs--of employer-sponsored health benefits. This paper argues that the widespread use of defined-contribution plans, with more consumer choice and more knowledgeable consumers, will lead to the erosion of the social contract on which health insurance must be based, with healthier employees subsidizing the care of older and sicker ones, and a death spiral of adverse selection. If unchecked by government intervention, these trends will lead to the collapse of employer-sponsored health insurance.
